LOUIS, OF SAME PLACE.

GRAIN- DRl-ER.

SPECIFICATION forming part of Letters Patent No. 251,372, dated December 27, 1881.

Application filed June 17, 1881. (No model.) I

To all whom it may concern- Be it known that I, EUGENE LOUIS, a citizen of France, residing at Montgomery, in the county of Kane and State of Illinois, haveinvented an Improved Grain-Drier, of which the following is a specification.

My invention consists in a new and peculiar construction of furnace and combination of the same with a drying-pan and stirring apparatus for drying malt, corn, and other grains, so that the bottom and sides of the pan containing the grain to be dried are practically exposed to the full heat of theproducts of combustion developed by the fire in the furnace.

My apparatus is particularly adapted in cases where it is requisite to dry corn, malt, and other grains quickly by means of heat, to prevent the setting in of putrid fermentation before the drying is completed.

Figure 1 is a side elevation, showing the furnace, drying-pan, and stirring apparatus. Fig. 2 is a top view of the same. Fig. 3 is a vertical section through the furnace and drying-pan on the line 00 m, Fig. 1; and Fig. 4 is a horizontal section of the furnace on the line y 3 Fig. 1.

A is the furnace, built of masonry, and constructed in such manner as to properly support and embrace the drying-pan B. The drying-pan B is supported upon the walls a and b of the furnace, and is embraced by the outer encircling wall, at, that is raised above the other parts of the furnace, as shown. The pan B, when in position, will securely close the top of the furnace A, all as shown in Fig. 3, and constitute the top of the combustionchambers.

Between the inner supporting-walls, a and b, and the outer wall, 01, are formed the flues or channels e f g. (More clearly shown in Fig. 4..)

Beneath the drying-pan B and between the walls a of the furnace A is the grate O.

h is the ash-pit, and k are the fuel-receivers.

The products of combustion developed by the fire upon the grate 0 pass into the channel e beneath the middle of the drying-pan B, thence into the inner annular channel,f, and

from there into the outer annular channel, g, which surrounds the sides of the drying-pan, and is formed on the inner side of the outer raised wall, d. From this channel 9 they cs cape into the chimney D. Thus it will be seen that the entire lower face and also the circumference of the drying-pan and the grain contained therein are subjected to the heat of the furnace.

Upon the drying-pan B, or upon the furnace A, is set the frame E, which supports the stirrer F and its shafting. This stirrer F has two, or more or less, stirring-blades, p, which enter and fit the pan B, and which are attached to a shaft or stem, q, that is coupled to a shaft, 1', hung in the upper part of frame E. The shaft 0 carries a bevel-pinion, I, that meshes into another bevel pinion, l, that is mounted upon the driving-shaft n. G is the coupling-piece for uniting the shafts q and 1'. By means of this coupling piece the stirrer proper can be readily disconnected from and reunited to the rotating mechanism. The blades of the stirrer are placed at an angle or inclination to the bottom of the drying-pan, so that the blades will readily move the grain.

The grain is placed in the pan and the stirring apparatus put in operation, the heat of the furnace reaching around and below the drying-pan, quickly and evenly performing the operation of drying the corn, malt, and other grains. The stirrer prevents the corn from being burned.

I claim- In a grain-drier, the combination of the furnace A, having flue 6 above grate 0, channel 1'', surrounding the flue e, and channel g, surrounding the channel f, with the pan B and suitable stirring apparatus, all arranged so that the products of combustion will pass directly beneath the bottom of the drying-pan through the flue c and channel f, and around the sides of the drying-pan through the raised channel g, substantially as herein shown and described.

EUGENE LOUIS.
